Re: Are beta blockers supposed to allieviate all cardiac related symptoms?
Well, the dosing depends on what you're on it for, exactly.
For thyroid storm (unlabeled usage), dosing is recommended to be Oral, 60-80 mg every 4 hours.
For thyrotoxicosis (also unlabeled, probably what you are using it for?) Oral, 10-40 mg/dose every 6-8 hours.
So, at 10 mg 3x/day you are on the low end. You could probably ask for a dose hike, but realize that the shortness of breath is a side effect of non-selective beta blockers such as propranolol.
